The creators of Zeega, an interactive digital storytelling platform on the web, recently launched their new mobile app, Pop! As explained on their website, Pop is about putting two things together. Capture a photo or video and combine it with anything on the web—an animated GIF, a movie clip—whatever comes to mind. To experience a Pop, press and hold down to reveal what’s underneath. Many Pops are funny—the app is perfect for the art of setup and punchline. But Pop can also be used to tell impactful stories.
